Robert made his first recording with the British progressive rock band Catapilla in the early 1970s. Then he studied improvisation for 4 years in London with Maggie Nichols and John Stevens. Between 1976 and 1980 he was a member of the critically acclaimed, freely improvising band John Stevens Away. During the 1990's extensive tours followed in Britain, Europe and the USA, with cult bands Mothergong and Gong.
Since 1994 Robert has pursued his passion for collective improvisation within the Howley Calvert George Trio.
Musician extraordinaire, powerfully lyrical saxophonist with a plaintive and seductive sound, Calvert rejects categorization and is concerned mainly with the spirit and meaning of music.
